STALL-FLOOR.

SPECIFICATION forming part of Letters Patent No. 463,244, dated November 17, 1891.

Application filed January 9, 1891. Serial No. 377,247. (No model.)

To all whoml it may concern:

Be it known that I, ALEXANDER R. SMITH, of Brooklyn, in the county Vot' Kings, and in the State of New York, have invented certain new and useful Improvements in Drain-Floors for Stalls; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which- Figure 1 shows a perspective view of my improved drain-floor for stalls in place; Fig. 2, a longitudinal section of the same on a plane passing between two of the slats; Fig. 3, a transverse section on line 0c a: of Fig. l; Fig. 4, a similar section on line 1/ y of Fig. l; and Fig. 5, a detail view in side elevation of a portion of one of the slats, showing the locking pin or rod in place in the side' groove therein.

Letters of like name and kind refer to like parts in each of the figures.

The object ot my invention is to provide an improved drain-door for stalls; and to this end my invention consists in the drain-floor, in its combination with the surrounding flooring, and in the construction, arrangement, and combination of the parts of the drainioor, as hereinafter speciiied.

The special purpose which I have had in view has been to produce a drain-Hoor which, while being capableof securing thequick and thorough draining away of all water frorn'the stall, so that the occupant of the latter will always have a dry surface to stand or rest upon, will be simple and cheap in construction, not liable to get out of order or become disarranged during continued use7 and will be capable ot being put together or taken apart easily.

It has also been my purpose to so arrange and construct the device that, while the slats will be held most firmly and securely in place and prevented froin'warping, any one ot' said slats can be readily removed when worn and replaced by another.

As will be Aseen trom the drawings and the description hereinafter given, I have also in my drain-Hoor provided. for a water-tight joint or connection between the sides and u pper or inner end ot' the base and the surrounding plain flooring which shall eitectually prevent any passage of liquid beyond said sides or end and under the flooring.

In the drawings, A A designate the plain flooring which surrounds the space to be ocpied by the drain-floor to be described. Such flooring can be supported in any desired way, as by battens or timbers d a on its under side or by other supporting devices.

IVithin a rectangular space in the center of the stall-flooring is situated the base Bi of my drain-floor, consisting of a plate, preferably of cast or wrought metal, having on its upper side the series of longitudinal ribs B B and a flange B2, extending along its sides and across its upper or inner end. As the plate, in order to secure the desired drainage, is to stand at an angle inclined downward and rearward toward the rear end ot the stall, the ribs B B are, as shown in the drawings, made diminishingl in height toward the upper end of the plate in order that their upper edges may be in a horizontal plane or parallel to the plane of the surrounding flooring. `rihe flange B2 is preferably made, as indicated in the drawings, higher than the ribs B B', so that its upper edge will stand in a plane above that of the rib-edges. The plain flooring around the space occupied by the plate is provided with a proj ecting portion a', extendingin over the flange, and has a groove a2, which receives the upper portion of. the latter. Then the drain-floor is put in place for use, it is my intention to white-lead this groove or the danger-top, or both, as indicated at a3 in the drawings, so as to make a thoroughly water-tight joint. Il desired, any suitable kind of cement can be used instead of the lead. y

The ribs B B are so arranged and constructed with reference to each other and the iiange along the sides of the plate as to lea've between them alternate narrow spaces b l) for gutters and wider rectangular ones b o for grooves to receive the strips or slats C C, of wood or other material, to forni the bearingsurface or tread of the drain-oor.- The gutter-spaces b Zi, which are preferably made V- shaped in cross-section, but not necessarily so, should bc arranged in such way that there shall be one of them at each side of the plate along the inner side of the ange on the lat- IOO Sired rearward inclination.

ter, as shown in the drawings. In the faces of the ribs, on opposite sides of the slat-receiving spaces or grooves, are the half-round grooves h2 b2, running along the ribs in a direction parallel to their upper edges. Each slat, of a sufficient thickness to bring its upper face on a level with the surrounding; plain flooring and having its under face inclined to correspond with the inclination of the baseplate B, has on it's opposite sides shoulders c c, parallel with its upper face, to rest upon the upper edges of the ribs, and downwardlyextending lips c c along the outer edges of the shoulders, adapted t9 extend down into the adjoining gutters l) b a short distance, so that all liquid ruiming down the sides of the slats will be guided into said glitters and will not tend to get in between the under sides of the shoulders and the rib-edges. In thesides of the slats, below shoulders c c, are longitudinal half-round grooves c2 c2, corresponding with those in the ribs and adapted to form with ythem round channels for the reception of the pins or key-rods D D, which when in place serve to lock and hold the slats securely down in the spaces between the ribs. For convenience in withdrawing the rods when desired the rear ends of the latter can be provided with the loops or eyes d, for the accommodation of which the ends of the slats can be recessed, as indicated at c3 in the draw ugs.

At the lower end of the base-plate the lower portions of the ribs and the bottoms of the gutters are extended outward and downward, so as to form lips c4 to discharge the contents of the gutters clear of the plate edge into the main drain E, to be described.

IVhile I do not in the drawings show any support for the upper end and body of the base B, it will be understood that any desired form of foundation or support can be used.

The watertight joint which I secure between the surrounding flooring and the flange B2 is intended to make the usual cement or Water-proof bed for drain-floors unnecessary, as it will eifectually prevent any water getting past the sides of the base-plate to the under side thereof. Battens or timbers can then be used for the plate to rest upon, made of the proper height to give the latter its de- -With the surrounding looring engaging the flange B2 no cement bed to hold the plate-supports or receive anchoring ribs or projections on the under side of the plate, as in drain-floors as heretofore made, is necessary. The connection between the iange and iloorin g tends to hold the plate in place. At its rear end said plate is shown as supported upon a crossbeam F, which also serves as a support for the forward or inner side of the transverse drain E, ma'defpreferably, of cast or wrought iron and having a lip E projecting forward under the discharge-lips c4 c4 on the rear ends of the longitudinal gutters on plate B. The front or inner edge of said lip E is turned up, so as to prevent any liquid iiowing from timber or beam F, and the other one being supported upon and fastened to another beam F', parallel to F. Any desired means of fastening can be employed. As shown, the flanges have screw-holes e e, through which screws can be driven into the supportingbeams. The part of the forward flan ge which projects under plate B is made plain and horizontal, its upper face being adapted to receive and support theunder side of said plate, while along the rest of the flange on opposite sides of the drain-lip E there is an upright rib E3, adapted to be engaged by a groove e in the supporting cross pieces or battens a of the plain iiooring. The flange along the rear edge of the drain is provided with a similar rib E4 to be received in a groove e2 in the ooring at the rear of the drain.

The described rib-and-groove connection between the drain-flanges and the surrounding flooring is to secure a water-tight joint to prevent anyliquid getting from the drain out under said ooring.

As in the case of the flange B2 on the plate B and the receivinggrooves therefor, the grooves egcan be white-leaded or provided with cement, as indicated at es, to insure the tightness of the joint.

Extending across the drain E on opposite sides of the plate B and resting upon the flanges along the drain edges are the crossbattens G G on the under side of the draincover G', whose forward and rear edges engage, respectively, the rear ends of slats C C and the forward edge of the flooring at the rear side of the drain. With the drain-cover thus supported above the flanges E2 E2 there will be a clear space left for liquid to run from the longitudinal gutters between the slats down into drain-lip E', and thence into the drain itself. Such cover, abutting at its rear against the flooring and at its front against the slatends, as described, will securely hold the slats against being worked longitudinally rearward by the pawing of the occupant of the stall and will cover the eye ends of the pins or key-rods D D in the recesses c2 c2.

While I show the flooring on the rear side of the transverse drain as lower than that at the sides of the drain-floor, it is not and does not have to be lower than the plane of the under sides of the rear ends of the slats, as it must be when the latter, as in the case of drain-floors heretofore lnade, are held in the grooves in the base-plate in such manner that they have to be moved longitudinally in or-v der to insert them in or remove them from their places.

With my drain-floor, the slats of which can be lifted directly upward from the holdinggrooves when they are unlocked for removal,

IOO

IIO

the rear llooring needs only to be low enough to admit the insertion or drawing out of the pins or key-rods D D. It does not have to be so depressed for allowing clearance of the slats as to make necessary holding-cleats to hold the drain-cover up against the ends of the slats when the latter are in place.

lhile the plate B is preferably made ot cast-iron, because such material withstands best the corrosive action of the liquid to which it would be exposed when usedin a stalldrain, and is shown as made in one piece with the ribs and flange B2, I desire it to be uuderstood that I contemplate making it, where desired, of other material, and constructing the flange or ribs separately and attaching them in any desired way to the body of the base. Said base can be thus built up in any desired way without departure from my invention.

The manner of putting in place my draindoor and its operation when in place will be easily understood from the foregoing description and the drawings.

The cross-drain is put in position with its flanges resting on the supporting timbers therefor, and the base B is then put down with its rear end'resting on the front ange of the drain and the beam supporting such liange and its body and upper end supported in any desired way to give the base-plate the proper inclination. The lips at the rear ends of the longitudinal gutters then project beyond the drain-flange and into the space within the lip or offset on the drain. The plain ilooring of the stall is now put down,with.its grooves engaging the iiange B2 on the sides and end of the base and the ribs along the ou'ter edges of the transverse drain-lianges. The joints thus made are rendered water-tight by being whiteleaded or cemented. The slats are put in place in their respective grooves and locked therein by the pins or keyrods inserted in the corresponding grooves in the slat and rib sides, and the transverse drain-cover is laid down so as to abut against the ends of the slats and the edge of the iooring at the rear side of the drain. During use of the stall with the drain-hoor thus put in place any liquid falling upon the floor will run oit of the sides of the slats down into the longitudi nal V-shaped gutters, from which it is discharged freely into the transverse drain. The downwardlyextending lips along the shoulders on the slat sides and the inner edges of the portions of the plain flooring which overlap the flange B2 at the sides of the plate insure afree delivery of the liquid down into the gutters and prevent its comingin contact with the upper portions of the ribs or flange.

The offset or lip on the front or inner side of the transverse drain affords a receptacle for receiving and guiding theliquid from the gutters into the drain and secures the prov tection of the discharge-lips at the rear ends of the gutters from injury when the drain is being cleaned out.

The slats locked down between the ribs on the plate by the pins or key-rodsin the man ner described cannot warp or getout of place,

while any one ot them can be readily removed when worn if the rods on opposite sides of it are drawn out ot the receivinggrooves in slats and ribs. rlhe insertion of another slat in place of the worn one is a most simple matter, the locking-rods being thrust back into position when the haltround grooves in the Slat-sides coincide with those in the plate-ribs.

My drain-floor1 constructed and arranged as described and shown, is cheap, simple, and easily made and has -its gutters and transverse drain easy of access for cleaning out and not liable to clog up. Its slats can be put in position or removed therefrom readily and without making necessary the removal of the base-p1ate or the surrounding flooring, and they are securely held in place and prevented from warping by locking devices easily manipulated to release or secure them at will.

Vit-h the water-tight connections between the surrounding iiooring and the base-plate and transverse drain the stable or stall can be constructed without the usual cement or other Waterproof bed under the ioor.

Having thus described my invention, what I claim is l. In combination with a drain-floor for stalls having a base provided along its sides witha lange,the surrounding tlooringgrooved to receive such liange, substantially as and for the purpose shown.
